Abstract: The present invention relates to novel antibody heteroconjugates and their use in the enhancement or inhibition of T or B lymphocytes. The heteroconjugate are comprised of at least two molecules cross-linked to each other, each antibody being reactive with a different cell surface antigen on the same cell. The heteroconjugates appear to act by binding to lymphocytes via the interaction of the antibodies of the heteroconjugate with their respective cell surface antigens and bringing those antigens into physical proximity to each other, resulting in enhanced or reduced activation and function of the lymphocytes. The heteroconjugates, methods and compositions of this invention are therefore useful in the regulation of lymphocyte function, resulting in the improvement of cellular immune responses in various disease states.

Title: Belt heater for conveyors
Inventor: DIXON STEVEN C
IPC: B65G15/38
Filed: 1990-10-18
Granted: 1993-10-05
Abstract: ABSTRACT        A conveyor belt is provided for carrying granular coal or ore from a mine or a crushing station, together with a belt heater in the form of a fuel burner which turns on to melt ice which as formed on the belt at temperatures below freezing.  The belt heater heats the conveyor belt surface to a temperature sufficient to melt the ice film to form water and thereby prevent the granular coal or ore from sliding to impair the conveying operation of the conveyor belt or to cause spillage from the conveyor belt.  When the conveyor belt stops, the fuel burner stops and thus prevents damage to the conveyor belt.  A preferred fuel burner is an oil heater.  An infrared heater can also be used but a fuel burner is preferred in flame contact with the belt. The flame of the fuel burner when used in direct contact with the conveyor belt can be immediately shut off when the conveyor belt stops and thereby prevents damage to the conveyor belt.  The flame temperature or air temperature reaches a value of at least about 400° C, preferably about 450° C to 850° C.  Electrical means are provided to shut down the fuel burner as soon as the conveyor belt stops.  Belt heater is useful even if no ice film is formed on the conveyor belt by heating the hinge or fold area of the folding conveyor belt.  An oil burner housing is provided with an air access door to permit debris dropping from the conveyor belt near the flame to be removed.

Title: Device for singularizing healds for warp-thread drawing-in machines
Inventor: BENZ RICO
IPC: D04B1/14
Filed: 1991-01-30
Granted: 2000-06-27
Abstract: The device contains a selecting member (21) for the healds (LI) fed in the form of a stack (LS), which selecting member (21) separates in each case the front- most heald (LI1) from the stack and makes it available for the drawing-in of the warp threads. The selecting member (21) is formed by a piston which can perform a stroke essentially transversely to the heald stack (LS), during the working stroke of which piston the healds (LI1) are transported from the heald stack (LS) into an intermediate position (ZP). A transfer means (24) for transferring the respective heald (LI1) to a transport unit (25) for transporting the heald to its drawing-in position is provided in this intermediate position (ZP).      All types of heald can thereby be selected from the heald stack, and neither a special preparation of the healds nor the use of a special type of heald is necessary. In addition, the heald separation and the further removal are completely uncoupled, which not only permits the use of means optimally adapted to the individual functions but also considerably simplifies the rectification of faults.

Filed: 1992-08-26
Granted: 1996-03-19
Abstract: Any valid displayed called number may be properly visually segmented by a call-processing arrangement (200) that uses stored definitions of syntax (320, 350) and grammar (400, 410) of the whole network numbering plan. The syntax definitions include definitions (312) of individual symbol strings and their associated display demarcations (360), if any -- such as spaces or dashes or parentheses -- or even their associated replacement strings. Display demarcations or replacement strings that are specified for individual symbol strings are administratively reprogrammable to change the specified display demarcations or replacement string. Following dialing of an individual symbol string, the symbol string is identified and it or its replacement is displayed (986) on the display (19) of the caller's telephone set (17) along with any previously-dialed symbol strings and is demarcated therefrom as specified in the definition of the symbol string. A caller thus always receives a display of any valid dialed number either properly visually segmented into its logical components or replaced by its logical meaning.
